Don Lemon will serve as anchor, live in Aurora (where he’s been reporting for days) to introduce the taped segments and to add any last minute information.

The hour includes profiles of the 12 victims, a feel for the event as seen through the prism of Columbine, a segment on the suspect with interviews with his former elementary school teacher and classmates, stories of ER doctor Comilla Sasson, father Tom Sullivan (who lost his son, Alex), a local gun range owner, and others. The documentary also profiles the city itself. Special attention is paid to the community’s efforts to block the suspect’s name. CNN is “trying to be sensitive…we are not glorifying him in any way,” a spokeswoman said.

Joanne Ostrow has been watching TV since before "reality" required quotation marks. "Hill Street Blues" was life-changing. If Dickens, Twain or Agatha Christie were alive today, they'd be writing for television. And proud of it.
